The root cause is that of->mutex allocated when opening a sysfs file read-only (which overlayfs might do) is confused with of->mutex of a file opened writable (held in write to sysfs file, which overlayfs won't do). Assigning them separate lockdep classes fixes that bunch and it's obviously safe" * tag 'pull-sysfs-annotation-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: kernfs: annotate different lockdep class for of->mutex of writable files14 April 2024, 18:41:51 UTC

d5cf50d Linus Torvalds12 April 2024, 17:05:10 UTCKconfig: add some hidden tabs on purpose Commit d96c36004e31 ("tracing: Fix FTRACE_RECORD_RECURSION_SIZE Kconfig entry") removed a hidden tab because it apparently showed breakage in some third-party kernel config parsing tool. It wasn't clear what tool it was, but let's make sure it gets fixed. Because if you can't parse tabs as whitespace, you should not be parsing the kernel Kconfig files. In fact, let's make such breakage more obvious than some esoteric ftrace record size option. If you can't parse tabs, you can't have page sizes. Yes, tab-vs-space confusion is sadly a traditional Unix thing, and 'make' is famous for being broken in this regard. But no, that does not mean that it's ok. I'd add more random tabs to our Kconfig files, but I don't want to make things uglier than necessary. But it *might* bbe necessary if it turns out we see more of this kind of silly tooling.

However, clang does not know that ksft_exit_fail_msg() will call exit() at the point in the pipeline that the warning is emitted because inlining has not occurred, so it assumes control flow will resume normally after ksft_exit_fail_msg() is called. Make it clear to clang that all of the functions that call exit() unconditionally in kselftest.h are noreturn transitively by marking them explicitly with '__attribute__((__noreturn__))', which clears up the warning above and any future warnings that may appear for the same reason.

It assumes that each device has a unique source ID. This assumption is incorrect and the VT-d spec doesn't state this requirement either. The reason for using a rbtree to track devices is to look up the device with PCI bus and devfunc in the paths of handling ATS invalidation time out error and the PRI I/O page faults. Both are PCI ATS feature related. Only track the devices that have PCI ATS capabilities in the rbtree to avoid unnecessary WARN_ON in the iommu probe path. Otherwise, on some platforms below kernel splat will be displayed and the iommu probe results in failure.

c064b53 Thomas Gleixner10 April 2024, 19:45:28 UTCx86/cpu/amd: Make the NODEID_MSR union actually work A system with NODEID_MSR was reported to crash during early boot without any output. The reason is that the union which is used for accessing the bitfields in the MSR is written wrongly and the resulting executable code accesses the wrong part of the MSR data. As a consequence a later division by that value results in 0 and that result is used for another division as divisor, which obviously does not work well. The magic world of C, unions and bitfields: union { u64 bita : 3, bitb : 3; u64 all; } x; x.all = foo(); a = x.bita; b = x.bitb; results in the effective executable code of: a = b = x.bita; because bita and bitb are treated as union members and therefore both end up at bit offset 0. Wrapping the bitfield into an anonymous struct: union { struct { u64 bita : 3, bitb : 3; }; u64 all; } x; works like expected. Rework the NODEID_MSR union in exactly that way to cure the problem.

The parser uses this value to initialize the SMT domain level. That's wrong because cpu_nthreads does not describe the number of threads per physical core. So this needs to set the CORE domain level and let the later parsers set the SMT shift if available. Preset the SMT domain level with the assumption of one thread per core, which is correct ifrt here are no other CPUID leafs to parse, and propagate cpu_nthreads and the core level APIC bitwidth into the CORE domain.

ffe3986 Steven Rostedt (Google)09 April 2024, 19:13:09 UTCring-buffer: Only update pages_touched when a new page is touched The "buffer_percent" logic that is used by the ring buffer splice code to only wake up the tasks when there's no data after the buffer is filled to the percentage of the "buffer_percent" file is dependent on three variables that determine the amount of data that is in the ring buffer: 1) pages_read - incremented whenever a new sub-buffer is consumed 2) pages_lost - incremented every time a writer overwrites a sub-buffer 3) pages_touched - incremented when a write goes to a new sub-buffer The percentage is the calculation of: (pages_touched - (pages_lost + pages_read)) / nr_pages Basically, the amount of data is the total number of sub-bufs that have been touched, minus the number of sub-bufs lost and sub-bufs consumed. This is divided by the total count to give the buffer percentage. When the percentage is greater than the value in the "buffer_percent" file, it wakes up splice readers waiting for that amount. It was observed that over time, the amount read from the splice was constantly decreasing the longer the trace was running. That is, if one asked for 60%, it would read over 60% when it first starts tracing, but then it would be woken up at under 60% and would slowly decrease the amount of data read after being woken up, where the amount becomes much less than the buffer percent. This was due to an accounting of the pages_touched incrementation. This value is incremented whenever a writer transfers to a new sub-buffer. But the place where it was incremented was incorrect. If a writer overflowed the current sub-buffer it would go to the next one. If it gets preempted by an interrupt at that time, and the interrupt performs a trace, it too will end up going to the next sub-buffer. But only one should increment the counter. Unfortunately, that was not the case. Change the cmpxchg() that does the real switch of the tail-page into a try_cmpxchg(), and on success, perform the increment of pages_touched. This will only increment the counter once for when the writer moves to a new sub-buffer, and not when there's a race and is incremented for when a writer and its preempting writer both move to the same new sub-buffer.

35f8342 Steve French04 April 2024, 23:06:56 UTCsmb3: fix broken reconnect when password changing on the server by allowing password rotation There are various use cases that are becoming more common in which password changes are scheduled on a server(s) periodically but the clients connected to this server need to stay connected (even in the face of brief network reconnects) due to mounts which can not be easily unmounted and mounted at will, and servers that do password rotation do not always have the ability to tell the clients exactly when to the new password will be effective, so add support for an alt password ("password2=") on mount (and also remount) so that we can anticipate the upcoming change to the server without risking breaking existing mounts. An alternative would have been to use the kernel keyring for this but the processes doing the reconnect do not have access to the keyring but do have access to the ses structure.

This wouldn't be hit when a device was formatted with durability=0 since in that case we'll only use it as a write through cache (only cached extents will live on it), but durability can now be changed on an existing device. - bch2_get_acl() could rarely forget to handle a transaction restart; this manifested as the occasional missing acl that came back after dropping caches. - Fix a major performance regression on high iops multithreaded write workloads (only since 6.9-rc1); a previous fix for a deadlock in the interior btree update path to check the journal watermark introduced a dependency on the state of btree write buffer flushing that we didn't want. - Assorted other repair paths and recovery fixes" * tag 'bcachefs-2024-04-10' of https://evilpiepirate.org/git/bcachefs: (25 commits) bcachefs: Fix __bch2_btree_and_journal_iter_init_node_iter() bcachefs: Kill read lock dropping in bch2_btree_node_lock_write_nofail() bcachefs: Fix a race in btree_update_nodes_written() bcachefs: btree_node_scan: Respect member.data_allowed bcachefs: Don't scan for btree nodes when we can reconstruct bcachefs: Fix check_topology() when using node scan bcachefs: fix eytzinger0_find_gt() bcachefs: fix bch2_get_acl() transaction restart handling bcachefs: fix the count of nr_freed_pcpu after changing bc->freed_nonpcpu list bcachefs: Fix gap buffer bug in bch2_journal_key_insert_take() bcachefs: Rename struct field swap to prevent macro naming collision MAINTAINERS: Add entry for bcachefs documentation Documentation: filesystems: Add bcachefs toctree bcachefs: JOURNAL_SPACE_LOW bcachefs: Disable errors=panic for BCH_IOCTL_FSCK_OFFLINE bcachefs: Fix BCH_IOCTL_FSCK_OFFLINE for encrypted filesystems bcachefs: fix rand_delete unit test bcachefs: fix ! vs ~ typo in __clear_bit_le64() bcachefs: Fix rebalance from durability=0 device bcachefs: Print shutdown journal sequence number ...11 April 2024, 18:24:55 UTC

36a1ca0 David Arinzon10 April 2024, 09:13:58 UTCnet: ena: Set tx_info->xdpf value to NULL The patch mentioned in the `Fixes` tag removed the explicit assignment of tx_info->xdpf to NULL with the justification that there's no need to set tx_info->xdpf to NULL and tx_info->num_of_bufs to 0 in case of a mapping error. Both values won't be used once the mapping function returns an error, and their values would be overridden by the next transmitted packet. While both values do indeed get overridden in the next transmission call, the value of tx_info->xdpf is also used to check whether a TX descriptor's transmission has been completed (i.e. a completion for it was polled). An example scenario: 1. Mapping failed, tx_info->xdpf wasn't set to NULL 2. A VF reset occurred leading to IO resource destruction and a call to ena_free_tx_bufs() function 3. Although the descriptor whose mapping failed was freed by the transmission function, it still passes the check if (!tx_info->skb) (skb and xdp_frame are in a union) 4. The xdp_frame associated with the descriptor is freed twice This patch returns the assignment of NULL to tx_info->xdpf to make the cleaning function knows that the descriptor is already freed.

bf02d9f David Arinzon10 April 2024, 09:13:57 UTCnet: ena: Fix incorrect descriptor free behavior ENA has two types of TX queues: - queues which only process TX packets arriving from the network stack - queues which only process TX packets forwarded to it by XDP_REDIRECT or XDP_TX instructions The ena_free_tx_bufs() cycles through all descriptors in a TX queue and unmaps + frees every descriptor that hasn't been acknowledged yet by the device (uncompleted TX transactions). The function assumes that the processed TX queue is necessarily from the first category listed above and ends up using napi_consume_skb() for descriptors belonging to an XDP specific queue. This patch solves a bug in which, in case of a VF reset, the descriptors aren't freed correctly, leading to crashes.

f7e4171 David Arinzon10 April 2024, 09:13:56 UTCnet: ena: Wrong missing IO completions check order Missing IO completions check is called every second (HZ jiffies). This commit fixes several issues with this check: 1. Duplicate queues check: Max of 4 queues are scanned on each check due to monitor budget. Once reaching the budget, this check exits under the assumption that the next check will continue to scan the remainder of the queues, but in practice, next check will first scan the last already scanned queue which is not necessary and may cause the full queue scan to last a couple of seconds longer. The fix is to start every check with the next queue to scan. For example, on 8 IO queues: Bug: [0,1,2,3], [3,4,5,6], [6,7] Fix: [0,1,2,3], [4,5,6,7] 2. Unbalanced queues check: In case the number of active IO queues is not a multiple of budget, there will be checks which don't utilize the full budget because the full scan exits when reaching the last queue id. The fix is to run every TX completion check with exact queue budget regardless of the queue id. For example, on 7 IO queues: Bug: [0,1,2,3], [4,5,6], [0,1,2,3] Fix: [0,1,2,3], [4,5,6,0], [1,2,3,4] The budget may be lowered in case the number of IO queues is less than the budget (4) to make sure there are no duplicate queues on the same check. For example, on 3 IO queues: Bug: [0,1,2,0], [1,2,0,1] Fix: [0,1,2], [0,1,2] Fixes: 1738cd3ed342 ("net: ena: Add a driver for Amazon Elastic Network Adapters (ENA)") Signed-off-by: Amit Bernstein <amitbern@amazon.com> Signed-off-by: David Arinzon <darinzon@amazon.com> Reviewed-by: Shannon Nelson <shannon.nelson@amd.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>11 April 2024, 09:21:01 UTC

17c5601 Arınç ÜNAL09 April 2024, 15:01:14 UTCnet: dsa: mt7530: trap link-local frames regardless of ST Port State In Clause 5 of IEEE Std 802-2014, two sublayers of the data link layer (DLL) of the Open Systems Interconnection basic reference model (OSI/RM) are described; the medium access control (MAC) and logical link control (LLC) sublayers. The MAC sublayer is the one facing the physical layer. In 8.2 of IEEE Std 802.1Q-2022, the Bridge architecture is described. A Bridge component comprises a MAC Relay Entity for interconnecting the Ports of the Bridge, at least two Ports, and higher layer entities with at least a Spanning Tree Protocol Entity included. Each Bridge Port also functions as an end station and shall provide the MAC Service to an LLC Entity. Each instance of the MAC Service is provided to a distinct LLC Entity that supports protocol identification, multiplexing, and demultiplexing, for protocol data unit (PDU) transmission and reception by one or more higher layer entities. It is described in 8.13.9 of IEEE Std 802.1Q-2022 that in a Bridge, the LLC Entity associated with each Bridge Port is modeled as being directly connected to the attached Local Area Network (LAN). On the switch with CPU port architecture, CPU port functions as Management Port, and the Management Port functionality is provided by software which functions as an end station. Software is connected to an IEEE 802 LAN that is wholly contained within the system that incorporates the Bridge. Software provides access to the LLC Entity associated with each Bridge Port by the value of the source port field on the special tag on the frame received by software. We call frames that carry control information to determine the active topology and current extent of each Virtual Local Area Network (VLAN), i.e., spanning tree or Shortest Path Bridging (SPB) and Multiple VLAN Registration Protocol Data Units (MVRPDUs), and frames from other link constrained protocols, such as Extensible Authentication Protocol over LAN (EAPOL) and Link Layer Discovery Protocol (LLDP), link-local frames. They are not forwarded by a Bridge. Permanently configured entries in the filtering database (FDB) ensure that such frames are discarded by the Forwarding Process. In 8.6.3 of IEEE Std 802.1Q-2022, this is described in detail: Each of the reserved MAC addresses specified in Table 8-1 (01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]) shall be permanently configured in the FDB in C-VLAN components and ERs. Each of the reserved MAC addresses specified in Table 8-2 (01-80-C2-00-00-[01,02,03,04,05,06,07,08,09,0A,0E]) shall be permanently configured in the FDB in S-VLAN components. Each of the reserved MAC addresses specified in Table 8-3 (01-80-C2-00-00-[01,02,04,0E]) shall be permanently configured in the FDB in TPMR components. The FDB entries for reserved MAC addresses shall specify filtering for all Bridge Ports and all VIDs. Management shall not provide the capability to modify or remove entries for reserved MAC addresses. The addresses in Table 8-1, Table 8-2, and Table 8-3 determine the scope of propagation of PDUs within a Bridged Network, as follows: The Nearest Bridge group address (01-80-C2-00-00-0E) is an address that no conformant Two-Port MAC Relay (TPMR) component, Service VLAN (S-VLAN) component, Customer VLAN (C-VLAN) component, or MAC Bridge can forward. PDUs transmitted using this destination address, or any other addresses that appear in Table 8-1, Table 8-2, and Table 8-3 (01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]), can therefore travel no further than those stations that can be reached via a single individual LAN from the originating station. The Nearest non-TPMR Bridge group address (01-80-C2-00-00-03), is an address that no conformant S-VLAN component, C-VLAN component, or MAC Bridge can forward; however, this address is relayed by a TPMR component. PDUs using this destination address, or any of the other addresses that appear in both Table 8-1 and Table 8-2 but not in Table 8-3 (01-80-C2-00-00-[00,03,05,06,07,08,09,0A,0B,0C,0D,0F]), will be relayed by any TPMRs but will propagate no further than the nearest S-VLAN component, C-VLAN component, or MAC Bridge. The Nearest Customer Bridge group address (01-80-C2-00-00-00) is an address that no conformant C-VLAN component, MAC Bridge can forward; however, it is relayed by TPMR components and S-VLAN components. PDUs using this destination address, or any of the other addresses that appear in Table 8-1 but not in either Table 8-2 or Table 8-3 (01-80-C2-00-00-[00,0B,0C,0D,0F]), will be relayed by TPMR components and S-VLAN components but will propagate no further than the nearest C-VLAN component or MAC Bridge. Because the LLC Entity associated with each Bridge Port is provided via CPU port, we must not filter these frames but forward them to CPU port. In a Bridge, the transmission Port is majorly decided by ingress and egress rules, FDB, and spanning tree Port State functions of the Forwarding Process. For link-local frames, only CPU port should be designated as destination port in the FDB, and the other functions of the Forwarding Process must not interfere with the decision of the transmission Port. We call this process trapping frames to CPU port. Therefore, on the switch with CPU port architecture, link-local frames must be trapped to CPU port, and certain link-local frames received by a Port of a Bridge comprising a TPMR component or an S-VLAN component must be excluded from it. A Bridge of the switch with CPU port architecture cannot comprise a Two-Port MAC Relay (TPMR) component as a TPMR component supports only a subset of the functionality of a MAC Bridge. A Bridge comprising two Ports (Management Port doesn't count) of this architecture will either function as a standard MAC Bridge or a standard VLAN Bridge. Therefore, a Bridge of this architecture can only comprise S-VLAN components, C-VLAN components, or MAC Bridge components. Since there's no TPMR component, we don't need to relay PDUs using the destination addresses specified on the Nearest non-TPMR section, and the proportion of the Nearest Customer Bridge section where they must be relayed by TPMR components. One option to trap link-local frames to CPU port is to add static FDB entries with CPU port designated as destination port. However, because that Independent VLAN Learning (IVL) is being used on every VID, each entry only applies to a single VLAN Identifier (VID). For a Bridge comprising a MAC Bridge component or a C-VLAN component, there would have to be 16 times 4096 entries. This switch intellectual property can only hold a maximum of 2048 entries. Using this option, there also isn't a mechanism to prevent link-local frames from being discarded when the spanning tree Port State of the reception Port is discarding. The remaining option is to utilise the BPC, RGAC1, RGAC2, RGAC3, and RGAC4 registers. Whilst this applies to every VID, it doesn't contain all of the reserved MAC addresses without affecting the remaining Standard Group MAC Addresses. The REV_UN frame tag utilised using the RGAC4 register covers the remaining 01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F] destination addresses. It also includes the 01-80-C2-00-00-22 to 01-80-C2-00-00-FF destination addresses which may be relayed by MAC Bridges or VLAN Bridges. The latter option provides better but not complete conformance. This switch intellectual property also does not provide a mechanism to trap link-local frames with specific destination addresses to CPU port by Bridge, to conform to the filtering rules for the distinct Bridge components. Therefore, regardless of the type of the Bridge component, link-local frames with these destination addresses will be trapped to CPU port: 01-80-C2-00-00-[00,01,02,03,0E] In a Bridge comprising a MAC Bridge component or a C-VLAN component: Link-local frames with these destination addresses won't be trapped to CPU port which won't conform to IEEE Std 802.1Q-2022: 01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F] In a Bridge comprising an S-VLAN component: Link-local frames with these destination addresses will be trapped to CPU port which won't conform to IEEE Std 802.1Q-2022: 01-80-C2-00-00-00 Link-local frames with these destination addresses won't be trapped to CPU port which won't conform to IEEE Std 802.1Q-2022: 01-80-C2-00-00-[04,05,06,07,08,09,0A] Currently on this switch intellectual property, if the spanning tree Port State of the reception Port is discarding, link-local frames will be discarded. To trap link-local frames regardless of the spanning tree Port State, make the switch regard them as Bridge Protocol Data Units (BPDUs). This switch intellectual property only lets the frames regarded as BPDUs bypass the spanning tree Port State function of the Forwarding Process. With this change, the only remaining interference is the ingress rules. When the reception Port has no PVID assigned on software, VLAN-untagged frames won't be allowed in. There doesn't seem to be a mechanism on the switch intellectual property to have link-local frames bypass this function of the Forwarding Process.

Using id directly in that case is incorrect, as it maps to the least significant 32 bits of the 64-bit pointer in mlx5_fs_dr_action and not to the pkt reformat id allocated in firmware. For the purpose of comparing whether two rules are identical, interpreting the least significant 32 bits of the mlx5_fs_dr_action pointer as an id mostly works... until it breaks horribly and produces the outcome described in [1].

7c6782a Cosmin Ratiu09 April 2024, 19:08:12 UTCnet/mlx5: Properly link new fs rules into the tree Previously, add_rule_fg would only add newly created rules from the handle into the tree when they had a refcount of 1. On the other hand, create_flow_handle tries hard to find and reference already existing identical rules instead of creating new ones. These two behaviors can result in a situation where create_flow_handle 1) creates a new rule and references it, then 2) in a subsequent step during the same handle creation references it again, resulting in a rule with a refcount of 2 that is not linked into the tree, will have a NULL parent and root and will result in a crash when the flow group is deleted because del_sw_hw_rule, invoked on rule deletion, assumes node->parent is != NULL. This happened in the wild, due to another bug related to incorrect handling of duplicate pkt_reformat ids, which lead to the code in create_flow_handle incorrectly referencing a just-added rule in the same flow handle, resulting in the problem described above. Full details are at [1]. This patch changes add_rule_fg to add new rules without parents into the tree, properly initializing them and avoiding the crash. This makes it more consistent with how rules are added to an FTE in create_flow_handle.
